Exploration and practice of the golden course construction of principles of chemical engineering based on “online and offline learning”

Principles of chemical engineering is a very important basic course for chemical engineering and related major students. Several problems are existing in the traditional course teaching. The golden course construction of principles of chemical engineering were explored and practiced, and some achievements were obtained. “Online and offline learning” combination curriculum was constructed. “Online and offline learning” is a hybrid teaching model, which uses superstar online learning platform to build online teaching resource database. Online learning is for students to preview before class and review after class. Offline learning is mainly classroom teaching activities. The organic combination of the two can effectively improve the depth of students' learning. Ideological and political education was strengthened. Micro video based on knowledge points was recorded. Diversified formative assessment was established. The course won higher students' evaluation. Excellent students' competition results were got and their innovation ability was improved.
